RESUMO
Among 41 people returned from Equatorial Guinea, 16 persons were infected with Plasmodium falciparum (39.02%) in Longlin County, Guangxi Zhuang Autonomous Region from October 2011 to February 2012. Among the 16 cases, Plasmodiumfalciparum was found in their blood smears of 15 cases, and 1 patient was diagnosed clinically as falciparum malaria. All the 41 people were once suffered from malaria and they received antimalarial drugs when they were in Equatorial Guinea. These imported malaria cases received the standard treatment and the foci were sprayed with insecticides. No secondary malaria cases were found. In conclusion, the measures of imported malaria control are effective. The persons returned from Equatorial Guinea have a high risk of malaria; therefore, it is necessary to strengthen the monitoring of malaria for the floating population from high malaria prevalent areas.
